Objectives: To evaluate the esthetic and functional rehabilitation of single implants delivering the final crown during second-stage surgery.
Materials And Methods: In 26 single-tooth implants, the impressions were taken immediately after implant placement to fabricate the final crowns. During the second-stage surgery, the screw-retained hybrid crowns were delivered. Six months to 3 years after placement of the crown, a modified pink esthetic score (PES) was measured. Additionally, the number of treatment sessions was recorded. The mesial and distal contact points and the static and dynamic occlusion were examined. Patients' satisfaction was measured using a questionnaire.
Results: In this retrospective study, 21 posterior and 5 anterior implants were included. The average pink esthetic score was 11.3 out of 14. The most frequent limitations were incomplete papillae and deficits of the alveolar ridge. The average number of appointments was three, consisting of impression taking and surgery consent, implant placement, and crown delivery. Average patients' satisfaction was 46.7 out of 50 and thus, extremely high.
Conclusions: The presented approach allows the second-stage surgery and delivery of the final restoration for single-tooth implants in the same session. As the peri-implant mucosa is adapted to the final restoration in the first place, a more natural emergence profile is achieved. However, there is an increasing risk for reduced or missing papillae. Patients' satisfaction is generally very high.
Clinical Relevance: A method for direct definitive prosthetic restoration during the exposure of single-tooth implants is examined, advantages and disadvantages will be described, and patient acceptance is validated.

Background: Tooth agenesis, particularly the absence of upper lateral incisors, presents substantial challenges for clinicians due to the associated bone atrophy, which limits the use of traditional implant solutions. Current options, such as endosseous implants combined with guided bone regeneration (GBR), often fail due to insufficient osseointegration in atrophic bone. This study aims to evaluate the effectiveness of custom-made, additively manufactured subperiosteal implants in addressing these challenges METHODS: This retrospective study assessed 16 custom-made subperiosteal implants used in 12 patients (10 females, 2 males; mean age 25 ± 2.

Objectives: The aim of this randomised controlled trial was to assess clinical, radiographic and patient reported outcomes of narrow versus standard diameter titanium zirconium (TiZr) implants supporting single crown restorations in posterior sites with limited bone width.
Materials And Methods: Participants requiring replacement of single missing posterior teeth with implant-supported crowns were randomly allocated into 2 treatment groups: narrow (3.3 mm) or standard (4.

Objective: To compare the influence of different emergence profile of implants in mandibular molar on the peri-implant soft tissue.
Methods: Forty-four implants were divided into two equal groups by mucosal thickness, ≥2 mm (group A) or < 2 mm (group B), and were randomly included in the test group and the control group. In the control group, the patients were treated by a prosthesis with no transmucosal modifications (subgroups A1 and B1).

Objectives: To study the clinical effect of the L-shape technique combined with concentrated growth factor on the horizontal bone defects of maxillary anterior teeth.
Methods: Twenty-five implants from 25 patients who underwent single maxillary anterior tooth implantation with simultaneous bone grafting were selected as the study subjects. Based on the bone grafting techniques, the patients were divided into a test group (L-shaped technique with guided bone regeneration combined with concentrated growth factor, 11 cases) and a control group (traditional guided bone regeneration combined with concentrated growth factor, 14 cases).
Patient-reported outcomes of esthetics, function and oral hygiene with single dental implants 10-15 years after placement: a cross-sectional study.

Aims: Little attention has been paid to patients' perception of function and esthetics with single dental implants. The aim of this study was therefore to describe patient-reported function and esthetic outcomes in single dental implants. A second aim was to study the objective esthetics in single dental implants.
